New HVAC Refrigerants: What They Mean for Energy Efficiency and the Environment

New HVAC Refrigerants: What They Mean for Energy Efficiency and the Environment. Big changes are on the horizon for HVAC refrigerants, but, for the moment, they won’t affect most homeowner’s AC systems. The new regulations under the AIM Act are more about environmental improvements than changes to your home’s comfort. The current refrigerant, R-410A, is being phased out in favor of new, more eco-friendly options with lower global warming potential (GWP). But don’t worry—your current system is still good to go, and at SmartHouse Heating & Cooling, we’re here to make sure you’re well-prepared for the future. Let’s dive into what this means for you!

What’s Changing with Refrigerants?

The latest refrigerant transition is part of a broader push toward environmental responsibility. R-410A, which has been the standard in many HVAC systems, doesn’t deplete the ozone layer, but its high Global Warming Potential (GWP) means it still contributes to climate change. To address this, the EPA has mandated a switch to A2L refrigerants, which are more eco-friendly. Here’s what you need to know:

• R-410A: Zero ozone depletion potential (ODP) but high GWP.
• A2L Refrigerants: Lower GWP, meaning they have a much smaller impact if released into the atmosphere.
• Applicability: All new residential AC units manufactured will use A2L refrigerants, starting January 1st, 2025. Existing systems will continue to use R-410A or other refrigerants like R-134a.

These changes are evolutionary, not revolutionary, and they won’t impact the day-to-day operation of your HVAC system. The primary difference is behind the scenes—the shift is about reducing the environmental footprint of refrigerants, not about changing the comfort or energy efficiency of your system. Systems that are currently using R-410A can continue to be maintained and serviced without interruption.

Key points:

• New systems will use A2L refrigerants starting in 2025.
• Existing systems can keep using their current refrigerant for the foreseeable future.
• The primary goal of the refrigerant change is to reduce greenhouse gas emissions.

How This Affects Your HVAC System

If you’re planning to replace or install a new HVAC system, it’s important to know that the new refrigerants, like A2L, cannot be retrofitted into older systems using R-410A. This change means:

• New Systems Only: A2L refrigerants will only be used in new HVAC systems. Your existing system, if it uses R-410A or R-134a, can continue to operate and be serviced.
• Phase-Out Timeline: Equipment manufactured before January 1, 2025, will still be allowed to use current refrigerants like R-410A. These refrigerants will be available for maintenance for years to come.
• Cost Considerations: As older refrigerants become less available, the cost of maintaining your system may rise.

This transition doesn’t affect your comfort or system’s efficiency. The new refrigerants perform almost identically to R-410A systems—meaning you won’t notice a difference in your home’s heating or cooling.

Key points:

• A2L refrigerants are only for new installations.
• R-410A will still be available for servicing current systems that use R-410A.
• Prices for refrigerants like R-410A are expected to rise as availability decreases.

Why Now Is a Great Time to Upgrade

If you’re thinking about replacing your HVAC system, now might be the perfect time to act. For those thinking about upgrading soon but don’t want to get hit with the price hike, upgrading now with a system that still uses R-410A may be the better option. Here’s why:

• Price Increases: HVAC manufacturers have announced potential price increases of 10-20% for systems using the new A2L refrigerants.
• Availability of Current Models: Equipment using R-410A can still be installed for a limited time while supplies last.
• Future-Proof Your Home: Upgrading now secures current pricing while still providing a modern, energy-efficient system

In addition, the current refrigerant R-410A will still be available for servicing these systems for years, giving you peace of mind that service won’t be an issue.

Why upgrading now makes sense:

• Avoid price hikes on new equipment.
• Benefit from current model availability.
• Enjoy a modern, energy efficient system now.

With impending refrigerant changes, upgrading your system can help you avoid future costs while still providing a high level of efficiency and comfort.
